This $1,153,105 federal Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) will fund collaborative research to study the impacts of virovory (virus consumption) on the cycling of carbon, nitrogen, and organic matter in marine ecosystems. The project will use isotope tracing and microbial food web models to quantify how virovory influences the sequestration of carbon and the transfer of nutrients and energy to higher trophic levels across different marine environments, from oligotrophic to eutrophic. The research aims to provide a more comprehensive understanding of the dynamic roles viruses play in the ocean's carbon cycle and the broader functioning of marine food webs. No subawards are planned under this grant, which has a project period from May 1, 2025 to April 30, 2028.
